摘要
对准一维有机铁磁体ｐｏｌｙ－ＢＩＰＯ体系的磁性机理进行了研究。详细考虑了该体系中的电子跳跃、电子关联及派尔斯不稳定性，自洽地计算了其能带结构和自旋密度分布，并数值地研究了各因素对系统特性的影响。结果发现该体系基态为稳定的铁磁态．
Abstract The ferromagnetic state in quasi-one-dimensional organic ferromagnet poly-BIPOhas been studied.We consider the electron hoping, electron-electron correlation andPierls instability in one-dimensional system. And self-consistent calculations are per-formed to investigate the structure of energy band and the distribution of spin den-sity.The effects of the above aspects on the ferromagnetic state are studied. Theresults show that the ground state is a stable ferrolnagnetic state in this system.
